Definitions

  • the invention relates to a rolling mill with several rolling stands and provided on the operating side of the scaffolds and slidable transversely to the roll axes support plates, which are equipped to accommodate sets of work rolls and adjacent to the mill hall.
  • the scaffolds are preceded by pits each on the operating side, the reason of which is to extend for supporting roller sets.
  • DE 43 21 663 A1 proposes to provide the pits, which are arranged between the rolling stands and the transversely displaceable support plate line, with pivotable flaps. These flaps are for work roll change in a horizontal position, while they give the support roller change by a folding movement, the pit for retracting the support roller sets.
  • this known rolling mill with over If there are any closable pits between the scaffolding line and the support plate line, the work rolls must be moved over the flaps to the support plates. Only on the support plates takes place the transverse displacement and the exchange of work rolls. The travel is therefore relatively long and correspondingly time consuming.
  • the present invention seeks to provide a rolling mill, in which both the work roll change and the backup roll change can be achieved within a short time sequence, in which the change can be made more efficient and thus the production time of the system can be increased can.
  • the core of the invention is that the support plates, which cover the pits immediately adjacent to the rolling stands and take over the transverse displacement for work roll change, also for the backup roll change individually for a particular scaffolding or completely for the entire rolling mill from the pit and thus scaffolding area partially or completely are movable.
  • the individual support plates are releasably connected to each other, so that either the entire support plate line or the support platform or only individual packages of support plates are movable.
  • individual scaffolds of a multi-stand installation can thus be equipped more quickly with new support rollers.
  • the used or new work rolls can remain standing on the support plates in the position for supporting roller change. Thus, this additional change time is eliminated with each backup roll change.
  • the traversing area necessary for the procedure of the support plate line is embedded in the hut corridor. He can also be covered with a cover, which forms the hut floor, so that the movement range for other functions, such as a storage space, is available.
  • Fig. 1 shows a side view of a rolling mill 1 with here six rolling stands (F1-F6), which are arranged firmly anchored on a foundation 2.
  • the rolling direction WR is marked with the arrow.
  • a pair of scissors 3 and a tinder scrubber 4 can be arranged.
  • BS operating side
  • a support plate line 6 is arranged from individual support plates 7, as shown in FIG. 2 is illustrated.
  • the support platform, i. the totality of all support plates 7, consists of one support plate 7 per rolling stand F1-F6.
  • These support plates 7 are arranged for working roll change above pits 8, which are located below the hut corridor 9 (see FIG. Subsequent to the framework region 5 extends, seen in the rolling direction WR, the outlet region 10 for the rolling stock.
  • This movement region 11, which is designed as a roller conveyor, is designed so long of its extent that all support plates 7 of the support plate line 6 in their entirety out of the frame region 5 are moved parallel to the outlet region 10 and thus all pits 8 can be released to change the support rollers 12.
  • a pit 8 In addition to a rolling stand Fi arranged on a foundation 2, there is a pit 8, on the basis of which exit rails 13 for the supporting roller sets 12 are arranged.
  • the extension movement is achieved by means of an extension-cylinder unit 15.
  • the respective pits 8 are covered in extension to the hut floor 9 with the support plates 7, which are provided with corresponding pairs of rails for extending and retracting the sets of work rolls 14.
  • Tractors (not shown) drag the used work rolls 14 'onto the support plates 7 and, if necessary, back into the roll workshop.
  • the transverse displacement of the support plates 7 for work roll change is accomplished by means of a hydraulic cylinder 16 (see Fig. 2).
  • the support plates 7 When a backup roll change is pending, the support plates 7 are moved over the pits 8 transversely to the roll axes in the travel area 11. The pits 8 are then available for retracting the support roller sets 12 and for changing the support rollers available.
  • all support plates 7 in their entirety or only subgroups 17 or subpackets of support plates can be displaced to open the pit 8 of a desired individual rolling stand, which is shown in FIG.
  • the support plates arranged downstream in the rolling direction are moved together with the support plate which is assigned to the fourth rolling stand as a package 17 by the distance from a support plate in the direction of the rolling direction WR.
  • the support roller set 12 of the fourth rolling stand F4 can be retracted and changed into the now open pit 8.
  • the travel area 11 for the displaced support plates 7 is arranged above the shed corridor 18 behind the rolling mill line.
  • the hut floor 18 in the outlet area is arranged in relation to the hut floor 9 in the frame area - lowered by about 350 mm.
  • Fig. 5 illustrates this, the arrangement of the support rollers 19 of the roller conveyor to promote the support plates 7 in the travel range 11.
  • the carrying rollers 19 are in lowered tracks 20 embedded in the foundation 2.
  • the carrying roller tracks 20 creates a relatively flat surface 21, which can be run over with vehicles such as a truck or a mobile crane. Overall, the support platform is moved over these carrying roller tracks 20 and the hut floor 18.
  • the support rollers may preferably be provided with a two-sided guide collar 22.
  • the traversing area 11 can be run over by vehicles, it must always be kept free in order to allow the mines to be opened.
  • the hut floor 23 is increased in the travel area 11 in relation to the hut floor 9 in the framework area, the support plates 7 extend over the support rollers 19 below the hut corridor 23 along the then between the rollers 19 open carrying roller tracks 24 (see Fig. 6).
  • FIG. 7 shows that the carrying roller tracks 24 themselves are provided with a cover 25, so that the support plates 7 or the support platform can be moved under the cover 25. In this way it is achieved that the cover plane and thus the hut floor 23 can be used above the movement level for other purposes.
  • a drive rod pinion 28 which is driven via a gear 29 by an electric motor 30 (compare FIGS. 2, 10 and 11).
  • the drive is composed for example of a DC motor, a spur gear, an electromagnetic gear coupling and a shaft that drive the drive pinion 28.
  • the drive pinion gear 28 engages in a drive train toothing 31 on the underside 32 of the individual support plates 7. So that the support plates 7 do not tilt during the movement, are Side guide rollers 33, which roll along the side surfaces of the plates 7, provided, which are also arranged on bearing blocks 34.
  • the support plates 7 In order to enable a movement of the support plates 7 as a complete package or as a support platform or as a sub-package, they must be detachably connected to each other.
  • the abutting plate ends 35, 36 are coupled by means of a particularly advantageous pin-and-spline connection, as illustrated in FIG. 12.
  • flanges 37, 38 are welded to the undersides of the plates, each having a bore for receiving a common pin 39.
  • the extending along the end portions 35, 36 of the plates pin 39 is guided by the flange 37 of a plate and secured by means of a holding plate 40 by means of screws 41, 42 and protrudes beyond the plate end 35 out.
  • guide elements 43 are arranged, which hold the bolt 39 radially and which are spanned with a locking plate 44.
  • the pin 39 engages the bore in the flange 38 of the other plate.
  • the second plate is positioned by means of a stop edge 45.
  • a wedge 48 is then introduced for locking.
  • the wedge 48 is removed and lowered into a wedge storage pocket 49 which is recessed into the plate surface adjacent to the pin 39.
  • a wedge-removing tool 50 is provided, as also illustrated with FIG. 13.
  • This wedge-removing tool 50 is composed of a hook 52 rotatably mounted on a rod 51 or lever, and two take-off rollers 53, 54 arranged below the rotary bearing.
  • the Abrückrollen 53, 54 which come to rest on the plate 7, ensure a large lever arm and a defined extraction point for the wedge 48th
